I am a new Mac user. I recently switched from using Jaws with Windows 7 to using OS X 10.10 Yosemite on a Macbook Pro. I had been figuring things out pretty well until I hit this particular snag. I've looked at several tutorials from this site and others, but I can't seem to figure out how to copy files and paste them into a folder. I have tried the copy and paste method as well as the drag and drop method and neither has worked for me. I have made sure that the Finder window that I am working in has been brought to the front of the screen. I have also made sure that cursor tracking is on as instructed by several tutorials. The keyboard cursor and VO cursors are set to follow one another. What I am trying to do is move some files from the root directory of an external hard drive to one of the folders on that drive.
At this point, I'm pretty frustrated and am not sure what else to try. I'm sure there is something very elementary that I am missing, but I can't seem to figure out what it is. Any help would be greatly appreciated.
